People subscribe to reality TV channels and plenty of guilty pleasures. OnlyFans is booming and so forth.
You may be correct, but I would love to see anything besides our wishful thinking that this would necessarily breed better content.
Not necessarily though - I can think of plenty of partially ad-supported media and publications that have retained their reputation for quality for decades or even centuries, for example, The Economist and the BBC World Service News channel.
...the thing is that the aforementioned don't generally run mass-market ads: the kinds of ads you see in the Economist or in-between World Service news segments is stuff like Rolex watches, Credit Suisse, and Chase Private Client Banking.
One is a subscription service, meaning they aren't reliant on their advertising for most of the finances.
The other is a quasi-govt entity, whose funding comes substantially from a tv license fee.
